I have upgraded to PHP 5.3.5 for a 1.13.2 wiki. I am now getting thousands of complaints in the virtual host error log of the form:
... PHP Notice: Undefined index: hash in <wiki root>/includes/Setup.php on line 75 ...
After some research these seem to occur because the default value of $wgLocalFileRepo set in Settings.php includes the array element:
'deletedHashLevels' => $wgFileStore['deleted']['hash']
I have googled this problem and found nothing reported.
Anyone here have ideas how to eliminate these?
